“…According to the current evidence firstly established by the WMAP experiment [1], the observed temperature and polarization anisotropies are consistent with the theoretical expectations iff the initial conditions of the Einstein-Boltzmann hierarchy are predominantly adiabatic and Gaussian (see also [2,3]). Every deviation from this concordance paradigm leads to entropic initial data (see e.g.…”

The adiabatic lore is then compatible with a minute tensor to scalar ratio r T provided some kind of plateaulike potential dominates, even before the onset of the inflationary stage, against the kinetic energy of the inflaton and against the spatial curvature [2].…”

“…The inflationary fluctuations of the Higgs field might also modulate the reheating process [13]. However, since it is reasonable to expect that the Higgs will decay before becoming dominant, the induced curvature inhomogeneities could be 2 The following notations for the Planck mass will be used throughout: M P = 1/ √ 8πG = M P / √ 8π where M P = 1. 22 × 10 19 GeV.…”

Even if the Higgs field does not affect the evolution of the background geometry, its massive inhomogeneities induce large-scale gauge fields whose energy density depends on the slow-roll parameters, on the effective scalar mass and, last but not least, on the dimensionless coupling to the space-time curvature. Since the non-Abelian gauge modes are screened, the non-minimal coupling to gravity predominantly affects the evolution of the hypercharge and electromagnetic fields. While in the case of minimal coupling the obtained constraints are immaterial, as soon as the coupling increases beyond one fourth the produced fields become overcritical. We chart the whole parameter space of this qualitatively new set of bounds. Whenever the limits on the curvature coupling are enforced, the magnetic field may still be partially relevant for large-scale magnetogenesis and exceed 10 −20 G for the benchmark scale of the protogalactic collapse.

“…The temperature and polarization anisotropies of the Cosmic Microwave Background can be successfully reproduced by assuming that the initial conditions of the Einstein-Boltzmann hierarchy are predominantly adiabatic and Gaussian [1,2]. Inflationary models are consistent with the presence of a dominant adiabatic mode but the smallness of the tensor to scalar ratio calls for a plateau-like potential in the Einstein frame implying a minute energy density of the inflaton in Planck units (typically ρ inf = O(10 −12 ) M 4 P ).…”

Stringy bounces and gradient instabilities

Bouncing solutions are obtained from a generally covariant action characterized by a potential which is a nonlocal functional of the dilaton field at two separated space-time points. Gradient instabilities are shown to arise in this context but they are argued to be nongeneric. After performing a gauge-invariant and frame-invariant derivation of the evolution equations of the fluctuations, a heuristic criterion for the avoidance of pathological instabilities is proposed and corroborated by a number of explicit examples that turn out to be compatible with a quasi-flat spectrum of curvature inhomogeneities for typical wavelengths larger than the Hubble radius.Comment: 25 pages; comments added and corrected typos; to appear in Phys.
